Subject RE: Preventing reading of a large XML file in memory
Date Tue, 17 Jul 2012 04:47:27 GMT
Thanks again.
I am using something like the following,

from(file.......).to(ejb:cms/CamelToPluginAdaptor/local?method=process(${header.CamelFileAbsolutePath},${properties:outbox}/${header.PROVIDER_ID}.xml,${header.PROVIDER_ID})

Where cms/CamelToPluginAdaptor /local is my EJB.

Will that prevent reading the whole file in memory?

thank you.

dont want the file component to read the whole file just pass along the file path to the bean?

Yes as the file component only stores the handle to the file. And only
read it on demand.
So in your bean, just pass in java.io.File, or a FileInputStream,
InputStream etc.
